This breakout season from Brandon Dubinsky is going to break the bank next summer. The same for his running buddy, Ryan Callahan, too, but the Rangers will take July salary-cap pain for 2010-11 gain.

It was 3-0 for the Blueshirts over the Devils last night at the Prudential Center, with Dubinsky scoring twice from around the net to increase his total to 10, tying him for the NHL lead with Steven Stamkos and Patrick Sharp.

Dubinsky’s two points boosted him into the club lead with 14, one more than Callahan (4-9), who was sidelined after falling awkwardly into the boards with a near face-plant in Philadelphia on Thursday, but is expected to be ready for tomorrow night’s Garden match against St. Louis.

“It comes back to confidence,” said Dubinsky, who has seven goals in his last seven games and has scored five of his team’s nine goals over the last four matches. “It’s a good feeling, but for me, I have to keep a level head and continue to do all the things that help you score.

“It starts in the defensive zone. Then it’s about getting to the net and competing in the dirty areas shift after shift. If you’re on the perimeter, you’re not going to get the bounces.”

Dubinsky is in the final year of a two-year deal under which he’s earning $1.85 million per. Callahan is in the final year of a two-year deal under which he’s earning $2.3 million per. If the Gold Dust twins keep it up the rest of the way, the Rangers have to figure that the combined cap hit on the impending Group II free agents will go from $4.15 million to at least twice that amount on long-term contracts.

That’s a primary reason why general manager Glen Sather has to be so careful acquiring players with contracts that go into next year. The 2011 summer cap that will include Wade Redden’s $6.5 million charge will loom large in every personnel decision the rest of the way.

But that wasn’t on coach John Tortorella’s mind when he praised Dubinsky following Henrik Lundqvist’s second shutout in his last four starts and 26th career whitewash.

“The success he’s getting, he’s deserved,” said Tortorella, who gave Dubinsky a shot at his first career hat trick with a shift in the final minute. “It’s still a process, but he’s stayed within himself, he feels good about himself and he’s handling himself the right way, too.”
